An optical information recording medium having a structure in which irregular reflection of information light and recording/reproducing light from the reflective layer of an optical information record medium is prevented, thereby reducing the noise appearing on the reproduced image. The optical information recording medium for recording information by holography comprises a transparent substrate, a recording layer where information is recorded by an interference pattern, and a filter layer formed between the transparent substrate and the recording layer and adapted to transmit a light of a first wavelength and reflect a light of a second wavelength. The filter layer of the thus structured optical information recording medium transmits a light of the first wavelength (for example, red light) and reflects a light of the second wavelength (for example, green light). As a result, two lights of different wavelengths can be separated and used for different purposes without being influenced by each other.
